* INET An implementation of the TCP/IP protocol suite for the LINUX
|
|
* operating system. INET is implemented using the BSD Socket
|
|
* interface as the means of communication with the user level.
|
|
*
|
|
* Holds initial configuration information for devices.
|
|
*
|
|
* Version: @(#)Space.c 1.0.7 08/12/93
|
|
*
|
|
* Authors: Ross Biro
|
|
* Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>
|
|
* Donald J. Becker, <becker@scyld.com>
|
|
*
|
|
* Changelog:
|
|
* Stephen Hemminger (09/2003)
|
|
* - get rid of pre-linked dev list, dynamic device allocation
|
|
* Paul Gortmaker (03/2002)
|
|
* - struct init cleanup, enable multiple ISA autoprobes.
|
|
* Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 09/1999
|
|
* - fix sbni: s/device/net_device/
|
|
* Paul Gortmaker (06/98):
|
|
* - sort probes in a sane way, make sure all (safe) probes
|
|
* get run once & failed autoprobes don't autoprobe again.
